[new build, slight issue.]

i took it to a car shop, they explained what was wrong ...I re wired my whole car with a way better quality LOC and amp kit. and he thru in some filters. Installed all that, has him tune my amp and no more noise.

thanks for all the help everyone

heres the system:

-Factory HU

-Scoshe Line out convertor with adjustable gains

-Autotek 1400.4 Amp

-Kicker KS68 Mids and Highs

-4ga wire

-Ground Isolator

Edit:

Dont know if this has any effect but the speaker wire from the passenger side is ran with the power wire (is that bad?)

either way pretty sure all of the speakers whine, but I will double check that.

Okay.so I fixed.the rca problem but I still have engine whine...i got a ground isolator loop and nothing happend...

I have tryed:

-Ground isolator loop

-checking all wires/connections

Can a Capacitor fix this?

Wait....do I need to run 2 sets of.rca cables for.a.4 ch amp?

No not yet, could it be the line out convertor positive n negitive wires mixed up?

4 channle amp

I only need one for it to work. The 2nd plug.has no affect. And do you mean get a.ground isolator?

[new build, slight issue.]

My new Mids and Highs are installed and so is the amp that powers it.

i'm using the factory HU and a LOC...now I only need ONE rca plug for the system to work...and it only works on the RCA input that says ch.2...and only the ch 2 speaker terminals produce sound. the others are either very quiet or nothing at all.

I also get Engine Whine.

possible solutions?
